    Chapter 4 Digital Input/Output and PFI • Buffered Change Detection Acquisition—A buffer is a temporary storage in computer memory for acquired samples. In a buffered acquisition, data is stored in the cDAQ controller onboard FIFO then transferred to a PC buffer. Buffered acquisitions typically allow for much faster transfer rates than nonbuffered acquisitions because data accumulates and is transferred in blocks, rather than one sample at a time.
